gteibo1Hi there!

Your description is a bit vague, lets see if i understood you correctly:

You have a tenat X and you are NOT going to setup a new tenant but just register a DOMAIN in the existing tenant x and want to change the UPN so that the users receive mail with the new Domain name?

You want to physically move mailboxes between Tenants?

Two totally different things here, let me know what you actually want to achieve and am happy to help. Done some 300+ migrations so might be able to help you 🙂

Hi we are also doing a migration from one Office 365 tenant to another in batches. the UPN is changing because they use mailto:firstname.lastname@domain.com

Source was mailto:firstinitial.lastname@domain.com

I have a question about Resource Room Mailboxes. Has anyone dealt with that.

Like how to handle Meeting Rooms when you migrating from Office 365 to Office 365 and your domain and upn are changing actually

Thanks
